When following the code example in the documentation for the overlap function to create aligned UDs, I get the following error: "Data not in single coordinate system". I've looked at the source code to see that that error is thrown when length(projection(data)) >1, but when I run that it returns a value of 1.
Here is my code:
guess <- lapply(nest.test$data, function(g) ctmm.guess(g, interactive= FALSE))
fits <- lapply(1:length(guess), function(i) ctmm.select(nest.test$data[[i]], guess[[i]]))
uds <- akde(nest.test$data, fits)
#Error in akde(nest.test$data, fits) :
# Data not in single coordinate system.
I will e-mail you now with a copy of my dataset, but I wanted to post this publicly in case the answer is helpful to others.
